applied to various automobile water tanks.The known heat-dissipating flat tubes for automobile radiators have the disadvantages of poor heat dissipation performance, large resistance to circulating water flow, easy to be blocked by scale, inconvenient maintenance, short service life, etc., and most of them are pulled through non-composite round aluminum tubes. Stretched, the heat transfer effect is not ideal.
The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an aluminum alloy porous flat tube for automobile radiator with obvious heat dissipation effect.
The technical solution adopted by the utility model to solve the technical problem is:
Automotive micro channel porous aluminum alloy radiator flat tube tubing comprises a flat tube body, wherein the flat tube body is internally provided with a plurality of circular through holes, and the circular through holes are uniformly distributed in the flat tube body.
The number of circular through holes is 10, and the diameter of the circular through holes is 0. 3~0.
The flat tube body is processed from an aluminum-manganese alloy.
Compared with the prior art, the utility model has the following significant advantages:
1. The utility model of automotive micro channel porous aluminum alloy radiator flat tube tubing, the flat tube body is still a conventional heat dissipation flat tube, and a plurality of through holes arranged inside are circular, so that the heat dissipation tube which is easily blocked by the flow rate is smooth and smooth. Enhanced heat dissipation.
2. In the prior art, automobile micro channel porous aluminum alloy radiator flat tube tubing re all made of copper tubes, and automotive micro channel porous aluminum alloy radiator flat tube tubing of the utility model are processed by an aluminum-manganese alloy, and the aluminum is replaced by copper and aluminized. The rate is over 85%, the weight can be reduced by more than 60%, and the service life of the automobile micro channel porous aluminum alloy radiator flat tube tubing is obviously improved.
3. The number of circular through holes of the utility model is ten. In the actual production process, it can be processed into 2~15 according to needs, and is suitable for various types of automobile radiators.
